Variant data vs Flattened to string

Similar Questions

• Connection (or not) the entrance to 'type' of function 'variant data?

  I noticed (again i) assumed that when I connect an output "Data Variant" connector of a VI or a known type indicator, the thread automatically adopt the correct type. Exports means that I don't have to connect a wire to the 'Type' of the 'variant data?

  There are many similar situations where this shortcut does not work. For example, the variant of wiring data function for a bundle by node Name will automatically select the target type of the conversion. I suppose that the index case is a very specific optimization, and this isn't a generally available shortcut.

• How to create a Subscriber variable to the network & OnDataUpdate for Variant data type?

  Looking at the example C:\Documents and Settings\All Users\Documents\National Instruments\MStudioVS2008\DotNET\Examples\NetworkVariable\Basic\cs\Subcriber.2008, how can I create a subscriber to the network variable and OnDataUpdate for Variant data types?

  All tracks will be useful. Thank you.

  I solved it by using the correct data type in .NET, for example an sbyte to CVIInt8.

• variant data

  I have a data type variant. See attachament. I tried to use varying data for each values within the Variant.

  Is it possible to extract or obtain values of each in a variant data type? How do you usually?

  Thank you

  You must connect a data type to the variation of data to determine the conversion. /Y

• Date field - allows any string?

  I use a date and time standard on LC form field, data format = date.  However, it allows users to enter any string and am need it being only date.  I'll put a schema validation, but before adjustment, want to be sure everything first, is - it normal, that a date field allows any string type to be entered manually (they used 30 September 2014 as their answer, and when I imported the answer in Access, of course, it is not passed on the side of the access of gathering in a date field).

  One thing I noticed, is that you must put your cursor in the date fields before the datePicker drop-down menu will appear.  Is there a future plan to have the spectacle of the down arrow even if there is no cursor in the field?  Just a request for 'improvement', as someone can not notice that and keep typing.  I had assumed wrongly a date field would only accept the date in the format data, then by way of solution, put validation schemas, but it has been the hope of a better understanding of this area for the future.  Thank you!

  Post edited by: sparrowce Information - when I test validation, have put all the necessary model date, in tests, it will give the error message if I get a string, and then the field always accepts the string.  I need to know how to correctly validate the date field, thank you!

  Hi, this is the standard behavior and is the same for a decimal field when you add a format of edition as num {$zzzz9.99} you can type what you want.  So, you'll need validate the value yourself.  If the value entered corresponds to the model to edit then it will be converted to the format YYYY-MM-DD in-house, then the invalid value will be copied as it through.  This means that as long as your display template is YYYY-MM-DD an invalid date will be one who possesses a formattedValue == rawValue.  You may need to change multiple formats as well allow different formats to enter.

• Display the name of the tag as the column name and the value in the tag as a row of data from the input string.

  Hi Forum members,

  I am looking for a query display the name of the tag as the column name and the value in the tag as a row of data.

  I have to print the values within the tag to a file by choosing the value of the flags. the sequence of the tags will vary each time, as the tag name will change dynamically.

  So here is the example of input data and the expected output. The string in the text column must be separated as the column names and values.

• Problem reading video image from the camera IP Axis - confusion of variant data buffer.

  Hi there;

  I am writing a VI for an Axis IP camera.  He went to work, but I need to extract individual video stream images so I can overlay text using the functions of text IMAQ overlay.

  The thing is when I take a picture using the axis dll library (GetCurrentFrame), it returns a buffer size and a Variant representing the raster data.  The data is = 921 640 bytes representing a 40 byte header, and then the 640 x 480 x 3 raster data.  When I run the vi, I get a correct value for the size of the buffer (921 640) so I know it works.

  What don't understand me, it's the video image is placed in a buffer of type variant.   I don't quite know how to extract the raster data of the data type of "buffer" which is a type variant.  My apologies, I'm a bit ignorant in how to handle the types of "Variant".

  Does anyone have a suggestion?

  This is the VI

  Hi Peter,.

  Just to confirm, what IMAQdx version do you use?  You want to get the version 2010.3 since it is the latest version: http://joule.ni.com/nidu/cds/view/p/id/1641/lang/en

  The next issue would be that the Ethernet cameras discover is not necessary and that it is only used for GigE Vision cameras. The VI was named before IP camera support has been added and the name is unfortunately confusing now. In any case, the discovery of cameras takes place in the background and is automatic. The VI list must list your camera. It may be worth trying just to see if the camera appears in first MAX. Note that the IP camera must be installed on your local subnet, so it can be discovered.

  Regarding the examples, virtually none of the IMAQdx examples included in help-> find examples should work.

• data written in excel string is text rather than double when opened in excel

  I have the code that combines a time, many double arays string and some double rooms. Everything seems to work fine, except when I open the data file created in excel, the first cell after the time string is always a string and not digital. It is the first value in a double guard and all other elements in the array are correctly converted to numbers. Only the first element is misinterpreted. Is spoil other wise nice worksheet.

  Any thoughts?

  You already have the strings in a spreadsheet format.  Use Cancatinate strings instead of build table and then use the function Write Text File.  That could be the cause of all kinds of confusion for Excel.

• LV 2012 Flatten To String / string problems Unflatten

  I use a simple flatten to a string in order to save a setup of controls, then a unflatten string read saved orders.  The problem is when I try to read the file, it returns an error message:

  122 error to Unflatten string in front Panel.vi Installer

  Possible reasons:

  LabVIEW: The resource you are trying to open was created in a newer version of LabVIEW and is not compatible with this version.

  Which is wrong, because it was created in the same VI about 8 seconds earlier.  Are there known issues with this, or any places that I might want to watch?

  Edit: This code correct, unchanged compared to now was working last night without problem.  In fact, the saved files, I have tested with last night are still working fine, but do not load recently saved files.

  
  

• Strict Variant data

  What I get as output is

  

  The problem is that I simply quoted text. Most of the ways I tried to do (flatten chain) or enter the properity nodes does not work.

  Any suggestions?

  (The goal is to automatically to load/unload the clusters without carring what they store in their own country).

  What you need is the data type of the control, and not on his label. This vi is probably what you need: vi.lib-> utility GetTypeInfo.vi-> VariantDataType folder.

• Variant data type conversion

  Hi all

  I use VI Scripting in LabVIEW 2010. I need to know the data type of the wire connected to a Terminal. Terminal wire reference gives a property called "Datatype". I thought that this will help me. But he is a variant and how do I actually convert the data to find out the data type. Specifically, I want to make use of data type of cluster. How do I know if the wire is of type cluster?

  Thanks for any help.

  You want to use the 'GetTypeInfo.vi' VI "LabVIEW 20xx\vi.lib\Utility\VariantDataType\" folder for this!

  I would recommend installation of this Package of VI because it adds these features to pallets:

• Saving data to database access string result

  I have problems when I try to save the string result data (or data additional.) to a database.

  I think I need to change the schema of the database but don't know how.

  I have attached a simple VI, a sequence and a database to illustrate the problem.

  Appendix is a screenshot of the error message this test bench throws up.

  I use TestStand 4.1.1

  Can someone tell me how to overcome this problem.

  Thank you

  Doogle-

  The DATA field in the PROP_RESULT in the PLAY.mdb table is defined as a data type of 'Number' instead of the type of data 'Text' as in the default database file included in TestStand. Somehow this type of data has changed. If restore you, it must record the channel. I noticed that the string value that you connect is binary, so TestStand will record this in a binary encoded format that might not be what you want.

• Date conversion madness! String to date and vice versa

  Hello, I am working on an application targeting the OS version 4.5.x. I read a lot of messages and the links on this topic and can't seem to make the correct code.

  OK, here's the problem. I ask a timestamp date string to a server. The timestamp is the local time on the server (IS / PST etc.) and not GMT.

  My application must take time and subtract a number of days ranging from 1 day to 1 month. to get a "start" date The application must then provide the start and end date in a string format that it understands. Seems simple isn't?

  Here's the catch, however the time stamps should NOT be changed by the local what is using the device. For example, a device in Italy can contact the server located in Ottawa and ask a timestamp, the calculations shouldn't care about DST or time zone. Just take the supplied date and subtract a fixed number of days from her. Nothing more or less. This proved incredibly hard to do. first the HttpDateParser.parse (ServerTimeStamp) will be the subject of Date GMT and my problem is back to the zone specified in ServerTimeStamp.

  Thanks for any help in advance.

  My method

  public String getDAFIXMLRange (String ServerTimeStamp) {}
  String szRange;
  First analyze the incoming date and record them at the time of the last election.
  Day DAFIEndDate = new Date (HttpDateParser.parse (ServerTimeStamp));
  m_lLastPollTime = DAFIEndDate.getTime ();
          
  define the offset. Pre-programmed for simplification.
  lOffsetNumberOfSeconds long = 2 * 24 * 60 * 60;
          
        
  Calculate the start date by subtracting the offset. Multiply by 1000 to convert to milliseconds!
  Date DAFIStartDate = new Date (DAFIEndDate.getTime () - (lOffsetNumberOfSeconds * 1000));

  !!!!!!!!!!!!! HOW the DATEFORMAT OBJECT is used to get the output format ' yyyy-MM-dd' you HH: mm: "without the marker of time zone. The server knows that it is local to it. !!!!!!!!!!

  Now format the objects date as a string that includes the XML server.
  DateFormat DafiDateFormat = DateFormat.getInstance (); ' YYYY-MM-dd' you HH.

  !!!!!!!!!!!!!! THIS IS THE PART I'M CONFUSED on, with the HELP of zone to create the good date. !!!
  Time zone tz = TimeZone.getTimeZone ("IS");
  int adjEST = tz.getRawOffset ();

  Convert 'em in string format.
  String szDAFIStart = DafiDateFormat.format (DAFIStartDate);
  String szDAFIEnd = DafiDateFormat.format (DAFIEndDate);

  Replace the date calculated in the end segment ranges date XML.
  szRange = statItems.replaceAll (XML_DATERANGE, "TAGSTARTTIME", szDAFIStart);
  szRange = statItems.replaceAll (szRange, "TAGENDTIME", szDAFIEnd);
  Return szRange;
  }

  Hello

  Yes would be better if the server could provide you date to the GMT time zone, or date as a long.

  But if you can't ask the case on the server, one way might be to manually parse your string and create a new date of parameter values in a calendar, something like this

  Calendar cal = Calendar.GetInstance ();

  Cal.Set (Calendar.DAY_OF_MONTH, date)

  Cal.Set (Calendar.MONTH, month-1)

  Cal.Set (Calendar.YEAR, year);

  ' set the new time with the values, you must cal.setTime (cal.getTime ()-,...);

  and then put the date with SimpleDateFormat.

  I think that this could be a solution if you know the format string you recived that date and it won't change.

  I'm not sure but maybe it could be a solution.

  Kind regards
